Trial With Eribulin or Eribulin+ Endocrine Therapy in Locally-recurrent or Metastatic Breast Cancer Patients
- Registration Number
- NCT03795012
- Lead Sponsor
- MedSIR
- Brief Summary
Unresectable, ER-positive and/or PR-positive and HER2-negative locally-recurrent or metastatic breast cancer (mBC).
- Detailed Description
Pre- and post-menopausal women age ≥ 18 years with unresectable, ER-positive and/or PR-positive and HER2-negative locally-recurrent or metastatic breast cancer (mBC) with no prior line of chemotherapy in the metastatic setting, and that have shown progression while on an aromatase inhibitor-containing regimen in the metastatic setting or within six months from last aromatase inhibitor dose in the adjuvant setting. Patients must have received at least one taxane or anthracycline regimen in either the adjuvant or the neoadjuvant setting. Subjects must have adequate bone marrow and creatinine clearance functions.

- Arm && Interventions
Group Intervention Description Eribulin monotherapy Eribulin Patients will receive eribulin injections intravenously on days 1 and 8 of every 21- day cycle eribulin plus endocrine therapy Eribulin Patients will receive eribulin injections intravenously on days 1 and 8 of every 21- day cycle, in combination with endocrine therapy (aromatase inhibitor). AI must be identical to the last AI administered to the patient, whether in the adjuvant or metastatic setting.
- Primary Outcome Measures
Name Time Method The overall response rate (ORR) Baseline up to 27 months The overall response rate (ORR) in the eribulin + ET arms, defined as the proportion of patients with best overall response of confirmed complete response or partial response based on local investigator's assessment according to Response Evaluation Criteria In Solid Tumours (RECIST) criteria v. 1.11.
- Secondary Outcome Measures
Name Time Method The progression-free survival (PFS) Baseline up to 27 months The progression-free survival (PFS) for patients treated with endocrine therapy alone or in combination with eribulin is defined as the time from randomization until death by any cause or objective tumor progression based on local investigator's assessment according to Response Evaluation Criteria In Solid Tumours (RECIST) criteria v. 1.11.
The duration of response (DOR) in the eribulin and the eribulin + ET arms Baseline up to 27 months The duration of response (DOR) in the eribulin and the eribulin + ET arms, defined as the time from the start of the treatment to disease progression based on local investigator's assessment according to Response Evaluation Criteria In Solid Tumours (RECIST) criteria v. 1.11.
Maximum Tumor shrinkage Baseline up to 27 months Maximum Tumor shrinkage, defined as the percentage of tumor shrinkage from baseline (obtained from the sum of the largest diameters of the target lesions), based on local investigator's assessment according to RECIST criteria guidelines (version 1.1)1.
The clinical benefit rate (CBR) in the eribulin and the eribulin + ET arms Baseline up to 27 months The clinical benefit rate (CBR) in the eribulin and the eribulin + ET arms, defined as the proportion of patients with no disease progression after 6 months of therapy, based on local investigator's assessment according to Response Evaluation Criteria In Solid Tumours (RECIST) criteria v. 1.11.
PFS-2, in the eribulin and the eribulin + ET arms Baseline up to 27 months The PFS-2, in the eribulin and the eribulin + ET arms, defined as the time from the randomization to the second disease progression or death, i.e., PFS after the next line of treatment, based on local investigator's assessment according to Response Evaluation Criteria In Solid Tumours (RECIST) criteria v. 1.11.
Overall response rate (ORR) in the eribulin arm Baseline up to 27 months The overall response rate (ORR) in the eribulin arm, defined as the proportion of patients with best overall response of confirmed complete response or partial response based on local investigator's assessment according to Response Evaluation Criteria In Solid Tumours (RECIST) criteria v. 1.11.
The overall survival (OS) in the eribulin and the eribulin + ET arms Baseline up to 27 months The overall survival (OS) in the eribulin and the eribulin + ET arms, defined as the length of time that patients remain alive from the start of treatment (OS will be collected at the end of the study).
